The meeting commenced at 8:00 P.M. Members present: Robert Komitor, Chairman, CAC Dr. C. Alan Mason, Chairman, WCC Robert Hohberg Robert Funicello Gloria Allen Mary Anne Johnson, Emeritus Also present: Clifford Emanuelson, Conservation Consultant Tom Leddy, Beautification Director Jane Moss, L.I.F.E. Director Caroline Silverstone, Town Liaison Bonnie Burdick, Larchmont Reservoir Committee Administrative Matters: The minutes for the March meeting were corrected and approved for distri- bution; the next scheduled meeting for the CAC and WCC is Thursday, May 29, 1986, at 8:00 P.M., at the Town Conference Room. It was requested that Paul Noto be added to the CAC's mailing list. Environment: A general discussion was held concerning sewage treatment upgrading; the Harbor Island site was approved. Attached is a fact sheet of the Mamaroneck Sewer District from the Westchester County Department of Environmental Facilities. Dr. Mason reported that Malcolm Pernie will assist in updating the Wetlands map; Mrs. Johnson requested that soil quality reports be done in conjunction with the update.

Cherry Lawn: Mr. Emanuelson reported a field check was done on the siltation basin. The developer has installed bails of straw about the concrete outflow structure. This does strain the overflow waters to some extent, but does not stop the siltation completely. Straw has been spread over the collected siltation material in the basin and on the surrounding banks. This practice slows run off and erosion. In order to have the siltation basin faction properly, the collected siltation has to be removed from the basin so that the silt-laden waters can collect in the basin, remain there long enough for most of the silt to precipitate and then flow out of the basin. The work that has been done is a poor stop gap measure. The collected silt in the basin needs to be removed and the basin maintained using regular maintenance procedures. Fusco Development: Mr. Funicello and Mr. Komitor attended the Planning Board meeting; the project was approved. Water Courses and Water Bodies: Mr. Hohberg reported that our streams are not trout streams. Garden Lake is filled to capacity with silt and must be dredged. "Stream Corridor Management," a basic reference manual, will be available at the Conservation Office. A general discussion followed regarding regulations and laws; a review committee was formed with Robert Funicello (Chairman) and Alan Mason and Robert Hohberg. Discussion was held on the hearings on improvements on the Hutchinson River Parkway; Robert Romitor and Alan Mason will meet with Ortwin Meyers to review the proposal. Page 3. Solid Waste Disposal: The job description and management plan for recycling was requested by the Supervisor; Mr. Emanuelson will forward a copy this week. Air and Noise: A discussion was held on the noise barriers on the Thruway; Robert Komitor will contact Mr. Altieri to assure the Town's involvement. New or Other Business: Revision of the L.I.F.E. contract is necessary. It was recommended that Item #1 be deleted; Mr. Leddy will contact Mr. Altieri and advise the Commission at a later date. A general discussion was held regarding the proposed eight mile loop trail involving Larchmont Reservoir and Leather Stocking Trails by John Varvayanis. It was generally agreed that this would be a suitable use of the area and suggested that this proposal be cleared with the Larchmont Reservoir Committee. There being no further business to discuss, the meeting was adjourned. Dated: April 17, 1986 MAMARONECK SEWER/DISTRICT WASTEWATER TREATMENT PLANT UPGRADING FACILITIES PLANNING PUBLIC PARTICIPATION PROGRAM FINAL FACT SHEET • The Mamaroneck Sewer District is currently engaged in a program to upgrade its facilities to bring them into compliance with State and Federal regulations. This includes . repairing or replacing .the sewage conveyance facilities as required to remove extraneous flows and as deemed to be cost-effective. It also includes the upgrading of the level of treatment at the sewage treatment plant in the. Village of Mamaroneck to meet specific effluent limitations. The program has: been underway now for several years and the first segment of the upgrading program is currently being constructed in the Village of Mamaroneck. The Mamaroneck Sewer . District comprises approximately 282 miles of sanitary sewers extending into seven (7) different municipalities. These sewers discharge into County intercepting lines which deliver the flow to a County-operated sewage treatment plant in the Village of Mamaroneck. Effluent from this treatment plant discharges into Long Island Sound. Planning for the remaining segments in the upgrading program in Mamaroneck is being undertaken in two phases. The first phase, which has already been completed, includes the preparation of the basis of design for - the rehabilitation of the collection sewers throughout the Mamaroneck Sewer District. It also provides general background planning information regarding wastewater flows generated within the District and projected over the 20-year planning period. This first phase of district-wide facilities planning resulted in the publication of a report in April, 1985. The improvements recommended in this report are currently being designed. - 1 - 3/11 /86 'F un s s s s n 4 ''1c rs . .' �5 S� t1TR'J'l7 y 7n{)�7.>{;{j T\tZtty`,rr{rR ...,,.,...} �..rT.-.... The second phase of the Facilities Planning program is now nearly complete. This phase involves all necessary planning for the upgrading of the Mamaroneck Treatment Plant. Topics which have been examined during this planning effort include: 1 . review of pertinent background information and data such as past records, plant records, historical concerns, etc. ; 2. establishment of design flows and loadings, as well as effluent performance criteria which will meet the new secondary= treatment regulations; 3. evaluation of alternative sites for the treatment facility; 4. identification and evaluation of alternative treatment processes; 5. environmental review of the alternative treatment processes and sites; 6. basis of design for diffusion of effluent as discharged vie a new outfall pipeline into Long Island Sound; and 7. selection of the most cost-effective and environmenta',k -sound treatment processes and site location. {� Q` L\Gj� Federal (USEPA) and State (NYSDEC) funding of eligible costs for the treatment plant upgrading have not yet been finalized. Cost estimates for the project will be presented at the public hearing and detailed estimates and other pertinent information is contained in the Phase 2 Facilities Planning -- Report. Report. The entire Phase 2 Report (Volume I - Facilities Plan and Volume II - Environmental Assessment Summary) is on display at the sites listed in the attached public notice.
